A layered Mn-based coordination polymer as an efficient heterogeneous catalyst for CO2 cycloaddition under mild conditions†
The cycloaddition of carbon dioxide into value-added chemicals is of great significance to reduce carbon emission. Herein, a Mn-based coordination polymer [(CH3)2NH2]2n[Mn3(L)2]n·nDMF·0.5nH2O (JLNU-104) has been constructed by the solvothermal reaction of 1,2,4,5-tetrakis[(4-carboxy)phenoxymethyl]benzene (H4L) with MnCl2. JLNU-104 is a 2D layered complex assembled with infinite Mn-carboxylate chains and semi-rigid L4− ligands. Moreover, the layered structures can be held together through C–H⋯π interactions to form a 3D supramolecular architecture. Thanks to the rich Lewis acid sites, JLNU-104 exhibits durable catalytic performance for the cycloaddition of CO2 with epoxides. This work provides an insight into the design of functional crystalline catalysts for energy conversion.
